Uses normal JavaScript assignments for state updates, as shown in the timer example where increasing seconds is a simple increment, reducing code complexity.

Builds a dependency tree at runtime to ensure computations like React components re-render only when needed, eliminating manual optimizations such as memoization.

Manages state outside any UI framework, making code decoupled, portable, and easily testable, as emphasized in its architectural freedom philosophy.

Applies transparent functional reactive programming for glitch-free, synchronous updates, automatically deriving state changes and propagating them precisely.
